Smith & Wesson 350 Legend 7.5in Stainless Revolver - 7 Rounds - When one hears Smith & Wesson, one of the first things that comes to mind is revolvers. Delivering maximum power for avid handgun hunters, Smith & Wesson engineers created the massive "X-Frame" which serves as the basic design for the most powerful production revolver, the S&W500. Smith & Wesson is back to turn heads with the release of the M350 Legend X Frame, the first production revolver to shoot the efficiently designed 350 Legend hunting calibers.
